Use: cd / ; tar -cf /dev/stdout . | (cd /disk2 ; tar -xpf  /dev/stdin)

You should use the -p option on restore.

Otherwise your /tmp directory will lose some write bits,
your /dev/null might only be writeable by root and other neat stuff
that will keep you busy for hours .... (Guess how I noticed)
